Windows Phone users also won't be able to tag people in photos or view the geotaxis of posted images.

The Instagram app also will be available only on Windows Phone 8.

"We wanted to make Instagram available to people with Windows Phones as quickly as possible, so we focused on creating an awesome experience with Instagram's core features," Instagram said in a blog post. "We're not finished, and our team will continue developing the Windows Phone app to keep releasing features and bringing you the best Instagram possible."

A good indicator of a successful smartphone is the apps available in its ecosystem. That's because developers want to expend resources building apps that will get the most bang for their buck—and these days that means building apps for Apple's mobile devices and Android smartphones.

Windows Phones has has a tough time gaining traction against its competitors. But it has picked up market share and is getting some of the more popular apps, such as Instagram and Waze, to come to the Windows Store.

In fact, Windows Phone increased its market share to 3.6 percent in the third quarter from 2 percent in the year-earlier period, according to data from IDC Research. That it is now getting Instagram—one of the top apps on the Apple Store and Google Play—shows that the device is finding its place in the smartphone market.
